BACKGROUND OF THE INVENTION

The present invention relates to attachment mounts for the front end oftrucks, which can be used to mount truck accessories such as but notlimited to snowplows, winches and cab racks for supporting vehicles.

A variety of truck front end attachment mounts are known. These aretypically after-market attachment mounts, which are oftenlabor-intensive to install. Kenworth Truck Company (Kirkland, Wash.)manufactures Class 6 and 7 trucks, and has recently introduced a newfront end, tapered chassis to these trucks. Kenworth has also introduceda front frame bracket package designed to fit its new, tapered chassis.However, Kenworth's front frame bracket package is labor-intensive andexpensive to install. Other known front frame truck attachment mountsare also cumbersome, labor-intensive and not designed to work withnon-standard chassis, such as Kenworth's new tapered chassis. Front endattachment mounts must also be strong and durable, as in the case ofsupporting cab racks, for example, the mounts must support thousands ofpounds of downward force.

Accordingly, there is a need for a new truck front end attachment mountwhich is strong and durable, which can be obtained relativelyinexpensively and quickly attached, and which can be used with differentchassis, including non-standard tapered chassis.

SUMMARY OF THE INVENTION

The objects mentioned above, as well as other objects, are solved by thepresent invention, which overcomes disadvantages of prior truck frontend attachment mounts, while providing new advantages not believedassociated with known attachment mounts.

In one preferred embodiment, an attachment mount is provided for thefront end of a truck having a vehicle chassis. The attachment mountpreferably includes a front member for supporting a front-end truckattachment, and a distribution member located in a front portion of thevehicle chassis. The distribution member may be attached to the vehiclechassis and to the front member, to spread stresses originating fromdownwardly-directed forces exerted on the front member by theattachment, to the front portion of the vehicle chassis.

The attachment mount may be used to mount various attachments to thefront end of the truck, such as but not limited to: a snow plow; awinch; a blade; a bumper extension for a pump or pump motor; and a cabrack for supporting vehicles.

Preferably, the method of attachment of the mount to the truckaccommodates trucks having differing vehicle chassis widths, so that theattachment mount may be used with full-width truck chassis, as well aswith truck chassis that taper, width-wise, in a forward direction. Theattachment mount may also be used with Class 4, 5, 6, 7 or 8 trucks, forexample.

In one preferred embodiment, a front portion of the front member is apartial tube with a generally U-shaped front cross-section. A frontportion of the front member may protrude from the front of the truck, tofacilitate mounting an attachment. The front member may have alongitudinal axis which includes two planar sections connected by adiagonal section. The front member may be directly attached to a bumperbracket of the truck, and may be indirectly attached to the distributionmember through a connecting bracket of the truck, such as a bumperbracket or a spring bracket.

The distribution member may include a metal plate with a portion, suchas a rear portion, that is preferably attached to the main frame of thetruck.

The attachment mount may include left and right pair of mounts, witheach left and right pair including a front member and a distributionmember. The attachment mount may also include a single, integrated mountthat ties in to both sides of the front portion of the truck chassis,such as using a single integrated front member, and a single integrateddistribution member.

In a preferred embodiment, the total weight of the attachment mount(e.g., left and right sides, including welding and painting) is lessthan about 100 pounds. More preferably, the mount's total weight is lessthan about 75 pounds, and most preferably is less than about 60 pounds.

In another preferred embodiment, a method for securing an attachmentmount to the front end of a truck having a vehicle chassis is provided.A front member is provided, configured to support a front-end truckattachment. A distribution member is also provided, located in a frontportion of the vehicle chassis. The front member and the distributionmember, which together form the attachment mount, may be attached to thevehicle chassis and to each other, enabling the attachment mount tospread stresses originating from downwardly-directed forces exerted onthe front member by the attachment, through the front portion of thevehicle chassis.

In a particularly preferred embodiment of the method of the presentinvention, during the process of securing the attachment mount to thefront end of the truck, the only preexisting truck parts that areremoved and replaced are fasteners.
